Specification of Letters Tatent.

To all whom it may concern:

'Be it known that I,-J0HN NEUMANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Sealing-Washers for Jars, of which the following is a specification.

My invention relates to improvements in sealing devices forjars, bottles, or the like.

Heretofore glass preserve and fruit jars have been sealed by fitting a band or ring usually known as a washer and formed of rubber or similar elastic material, around the jar neck and against the bead or flange formed thereon and compressing it upon the same by a screw or spring pressed cap.

The principal disadvantages of this'construction are that the washer is constructed of inaterial (rubber) which is comparatively to manufacture, is easily short lived, is quite costly and expensive rotted by the contaminating acids in the jar and in a number of cases fails to produce an air and liquid tight seal.

My improved device is designed to avoid these disadvantages and-to this end I construct mv washer of; strong paper such as certain kinds of straw and pulp board and dip orimmerse the washer in a molten mass of hot wax which penetrates the outer fiber and fills the interstices and when cold forms a thickcoatmg or covering which is squeezed in place between the jar neck, bead and cap, forming a' perfect air and. water tight seal.

' The objects of my invention are to produce a durable and long lived washer of very inexpensive material, and exceedingly cheap to manufacture, which cannot be injured or rotted by acids or other materials,

' and which when in position will form a perfeet seal.

These and other objects I accomplish as hereinafter set forth. in the following description and as particularly pointed out in the appended claims, reference being had to the accompanying drawings in which two embodiments of my invention are shown.

Figure 1, is a view of another form of my improved washer partially in edge elevation and partiallyin section. V

Fig. 2, is a fragmentary section through a section through the form of washer shown in Fig. Land fitted are corrugated 3, to stifien and strengthen the c0nstr11cti0n Patented Feb. 13, 1917.

Application filed April 5, 1916. Serial No. 89,022.

in place upon the jar, the top cap being omitted. a Fig. 3, isa top plan of the form of my improved washer shown in Fig. 1.

In referring to the forms of my invention shown in the accompanying drawings in detail, llkG'IlllIIlBIiLlS designate corresponding parts.

In the washer shown in the drawings, the body 8, is made hollow, being practically shape in cross section and as shown at 9, in Figs. 2 and and also provide annular grooves which can be filled with wax forming exterior wax rings 10 upon the sides of the washer.

the sides thereof The interior of the washer is also filled with wax as shown atll in Figs. 2 and 3.

Referring to Fig. 3, it will be noted that the U-shaped form of my-improved washer opens interiorly or toward the surface of the bottle neck around which it is fitted so that when the top cap is pressed down upon the washer it flattens-the same and squeezes the interior wax filling 11 inwardly.

This causes the waxlto fill all the small crevices and interstices. and forms a perfect air and water tight seal which cannot deteriorate or rot with age, or from contact with acids'and is therefore of a permanent and lasting character.

It should be noted that a portion of the hot liquid wax is of the paper inseparably combining with it and forming a composite paper and waxen surface.

' a preferred form of constructmnfor carrying my invention into efiect, the same 15 capable of a wide. range of variation, alteration, modification and change without departing from the spirit of the vention, I therefore do not wish to be limited to the construction herein shown and described, but desire to avail myself tions, alterations, modifications and changes as fairly fall within the scope of the appended claims or may be construed to come within the same.

While I have specified paper particularly as the material of which the washer is to be made, it should be understood that if desired that 'any'soft' flexible material of'a fibrous character such I as hemp may be em- 5 ployed.

What I claim as invention and desire to secure by Letters Patent is 1. An annular sealing washer, having an annular groove in the face thereof and a 10 waxy material in said groove.

2. An annular hollow sealing washer substantially U-shaped in cross section, and-a wax substance in the hollow portion of the washer of a consistency capable of being squeezed out bythe applicatlon, of'pressure 15 to the washer. 1

3. An annular hollow sealing washer, subtantially rU-sh p'ed in cross section and having annular grooves in its side portions.

In testimony whereof I have aflixed my 20 signature.

JOHN NEUMANN.
